DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without creative labor belong to the protection scope of the utility model.

[0024] Please refer to Figures 1-5 The utility model provides the following technical scheme:

[0025] Embodiment one: a gradient cooling multilayer composite drainage pipe extrusion setting mold, including die body 1, inner die 2 and outer thread die 3, the die body 1 is rotationally connected with outer thread die 3, and outer thread die 3 is provided with inner die 2, and the outside of outer thread die 3 is provided with second temperature sensor 9, and the outside of second temperature sensor 9 is provided with gradient cooling structure 4, and gradient cooling structure 4 is connected with circulating structure 5, and inner die 2 left side is connected with demolding structure 6, and demolding structure 6 is fixedly installed at the top of base 7, and the front side of demolding structure 6 is provided with controller 8;

[0026] Use extrusion equipment to extrude material into the cavity between inner die 2 and outer thread die 3, after heating and forming to the material, cool it, as shown in Figure 1 、 Figure 4 and Figure 5 Gradient cooling structure 4 includes annular cooling cavity 401, heater 402 and first temperature sensor 403, the outside of annular cooling cavity 401 is connected with heater 402 and first temperature sensor 403, annular cooling cavity 401 is equidistantly opened in die body 1, and the outside of outer thread die 3 is provided with second temperature sensor 9.

[0027] A controller 8 is fixedly installed on the top of the base 7. The controller 8 controls the heaters 402 at three different positions from the inside to the outside according to the data detected by the second temperature sensor 9. The heaters 402 are heated to the cooling water in the annular cooling chambers 401 connected to them respectively. The temperature of the first temperature sensor 403 is set to ensure that the heaters 402 are heated to the set temperature. The controller 8 can automatically turn them off. The cooling water in the annular cooling chambers 401 that are closer to the multi-layer composite drain pipe is heated to a higher temperature, thereby reducing the temperature difference between the inside and outside of the pipe, reducing internal stress, and making it cool evenly.

[0028] Example 2: Figures 1-4 As shown, the circulation structure 5 includes a connecting pipe 501, a circulation pump 502, and a water tank 503. The two ends of the connecting pipe 501 are respectively fixedly connected to the circulation pump 502 and the annular cooling chamber 401. The end of the circulation pump 502 away from the connecting pipe 501 is fixedly connected to the water tank 503. If the cooling water in the annular cooling chamber 401 is not replaced for a long time, it will affect its cooling effect. By opening the circulation pump 502, the annular cooling chamber 401 can be replaced, thereby saving water resources, reducing wastewater discharge, improving environmental protection performance, and further improving the cooling effect.

[0029] Example 3: Figures 1-4 As shown, the demolding structure 6 includes an automatic telescopic rod 601, a motor 602, a connecting plate 603, a first connecting rod 604, and a second connecting rod 605. When demolding the multi-layer composite drainage pipe, the operation controller 8 starts the automatic telescopic rod 601. The output end of the automatic telescopic rod 601 is fixedly connected to the motor 602. The automatic telescopic rod 601 drives the motor 602 to move to the right. The output end of the motor 602 is fixedly connected to the connecting plate 603. The end of the connecting plate 603 away from the motor 602 is fixedly connected to the first connecting rod 604 and the second connecting rod 605, so that the moving motor 602, the first connecting rod 604, and the second connecting rod 605 move to the right.

[0030] The first connecting rod 604 is fixedly connected to an external threaded mold 3 at the end away from the connecting plate 603, and the second connecting rod 605 is fixedly connected to an inner mold 2 at the end away from the connecting plate 603. This allows the first connecting rod 604 and the second connecting rod 605 to push the inner mold 2 and the external threaded mold 3 out of the mold body 1. At the same time, the motor 602 is started, and the motor 602 drives the first connecting rod 604 and the second connecting rod 605 to rotate, so that the first connecting rod 604 and the second connecting rod 605 drive the inner mold 2 and the external threaded mold 3 to rotate respectively. This allows the inner mold 2 and the external threaded mold 3 to be separated from the multi-layer composite drainage pipe, which can be directly removed by the staff from the right side. The external threaded mold 3 can make the outer side of the multi-layer composite drainage pipe threaded, which can enhance the pressure resistance of the multi-layer composite drainage pipe.
